^H works as expected but doesn't map to delete or back space

This may be related, but my back ticks work fine, however the dash and 
underscore do not.  Has anyone seen the same or have a workaround?

The above was in Fedora 17/Firefox 16.0.1/ShellInABox 2.14.  Works fine in 
Google Chrome, so I have my workaround.  :)

I also have problems with the dash/underscore key. It looks like it might be an 
issue with the newer versions of Firefox.
I was able to reproduce the problem with Firefox 18.0 on Ubuntu 12.04, and 
18.0.1 on Windows XP.
But it worked fine with 13.0.1 on XP and Iceweasel (Firefox) 10.0.12 on Debian 
Wheezy.

Also worked fine with Midori 0.4.7 on Ubuntu 12.04 and IE8 on XP.

Using Shellinabox 2.10 on Debian Wheezy.

I have problems with firefox (version 21) too... Running version 2.14 of 
shellinabox and in the Danish locale (at least) the following keys dont work 
"-" ,"_" , "+", "?" 

Most other special chars (pipes, hats, umlauts, tick and backtick) chars work 
fine..

The above 4 works in Chrome

I've similar issues with Firefox (currently 26) where the '- and _' key and the 
'# and ~' key (this is a United Kingdom English keyboard) don't work.  Again, 
fine on Chrome and even on IE8.

@ (in Chrome) and | (in FF and Chrome) symbols are not working. Danish keyboard 
layout.

I fixed + ? - _ < > in Firefox and tested on Windows/Linux/OS X. The new 
keyCodes are added in handleKey/fixEvent/keyDown.

For Macintosh keyboards it's a bit tricky it adds ESC in front of ALT 
combinations (and all keys work without the "1B"/"ESCAPE" char in front that 
gets added). I think there is a place for it in the code to get handled, but 
I'm not sure where to put it right now so it interferes as little as possible. 
I will be looking into a valid solution for Mac when I have dug a little more 
in the source code and understand the addition of modifier keys etc.

The original issue is about the backtick/quote so I will try to address that:

On my keyboard it reports as 187 in Chrome. I comment out case 187 in handleKey:
      //case 187: /* =            */ ch = this.applyModifiers(61, event); break;
(Which translates any ` or ´ to = - since they both trigger keyCode 187 at 
first.)

And now it works for me also in Chrome without outputting = everytime ´ is 
tapped. ("`=")

Hi, 

we have fixes for -, _, #, ~, <, >, + and * characters integrated in our fork 
on Github:
https://github.com/shellinabox/shellinabox

If you wish you can also create a pull request on our repo, as we are trying to 
maintain
shellinabox project with latest fixes.

And a little warning: you are trying to fix to vt100.js file, which is auto 
generated
from vt100.jspp. All you fixes will be over written when you update vt100.jspp 
file. So you
should fix that file.

Bye :)

#12:

That sounds great. Can you use my fix for "?" in that case?

Do you have a comment on the Mac+OPTION situation? To keep it simple the 
problem is as follows: 1B (hex) e.g. ESC is added to every ALT+ combination. Do 
you have a suggestion on where to put a condition? I was thinking maybe 
something an if statement that said "IF ESC+@" or another Mac key combination 
== strip ESC! Because I think the ESC hex char code is intended from the 
original code?

I will be investigating the jspp file now ;)

#13: 

Ok :)

I have taken another look at the issue and I found working patch in issue 202:
https://code.google.com/p/shellinabox/issues/detail?id=202#c23.

You just have to change the code in function keyDown(), for firefox to detect 
new 
keycodes as normal keys.

I have tested this patch on Slovenian, German and Danish keyboard and I think 
it works
fine even for "?" sing :) Can you also test this patch on your keyboard? I 
don't know what
kind of keyboard are you using :)

You can see commit here: 
https://github.com/shellinabox/shellinabox/commit/3570f20b0b0db1909bf19685128ed3
ae3a3445dd

As for the Mac, i don't really know what we should do yet. But I think i saw 
something
on Github that has to do with this ... I will try to find it again and will 
report back.

Hi, I am reporting back :)

I found this fix related to Mac: 
https://github.com/JGRennison/shellinabox/commit/d62c3368094b679071cd62ffbbe4bbe
970fb6f40

Please tell me if you can test this and it works for you. So I can integrate it 
in our fork. For
testing you can just clone this fork: https://github.com/JGRennison/shellinabox

With two above commits everything but ` ´ works.

I served you this pull request ^

Hi, glad to hear you got it to work. But I have to tell you that this is 
actually 
not my fork :)

If you wish you can also issue pull request here: 
https://github.com/shellinabox/shellinabox 
This is the one that I take care of and I will happily accept your patch :)

But I think that on "shellinabox/shellinabox" fork we still need to integrate 
changes from
commit d62c3368094b679071cd62ffbbe4bbe970fb6f40 ...
